Atomic absorption (AA) has been known since the 19th century, but it was not until the 1950s, thanks to efforts by Alan Walsh at Australia’s CSIRO research center, that use of AA spectrometers became routine for metals analysis. AA measures
Although serious Fourier-transform infrared spectroscopy (FTIR) research and core analysis facilities are still doing well, traditional applications are giving way to more dynamic uses such as controlling processes and field work. For research FT
GC was once commonly called “GLC,” where the “L” stands for liquid. Inside GC columns are particles of a ceramic or inert material coated with a viscous liquid stationary phase that interacts with the analyte. By contrast, HPL
Gas chromatography-mass spectrometry (GC-MS) is the fastestgrowing GC method. Mass detection, which can take a variety of forms based on the MS component, provides a dimension that conventional thermal conductivity or flame ionization detectors canno
Chromatographers who learned their craft twenty years ago may not have been familiar with autosamplers then, but today nearly every high performance liquid chromatography (HPLC) instrument includes an autosampler as standard equipment. “Aut
Now that sub-2-micron columns have become the stationary phase technology of choice for research labs and have made substantial inroads in quality, food, and pharmaceutical settings, another breakthrough in column technology looms.
As HPLC systems become faster and employ increasingly exotic stationary phases, sample preparation becomes essential for reliable, reproducible analyses. Biological samples generally require concentration in the target analyte and, in the case of
RNA interference (RNAi) uses short strands of synthetic ribonucleic acid (RNA) to silence or “knock down” genes implicated in certain phenotypes—most commonly (but not limited to) diseases.
Within a decade of its discovery in 1983, polymerase chain reaction (PCR) evolved into one of biology’s most useful tools. PCR amplifies specific segments of genes so accurately that an early National Institutes of Health publication dubbed the

Whether to employ central washing stations or point-of-use washers located under a lab bench is something that has to be addressed with regards to laboratory glassware washers. The former provide an economy of scale and are popular with lab workers w
Time-of-flight (TOF) mass spectrometry (MS) works by imparting equal energies to all fragments. Since smaller particles thereby travel faster, their masses are determined by how quickly they travel from the source to the detector.
Viscometers measure viscosity, the resistance of fluids to flow or stress. In common terms, viscosity is related to a fluid’s “thickness”—a physical property of great interest to manufacturers of liquids, slurries, and pastes.
Oil-free diaphragm pumps have earned a reputation for environmental- friendliness for low- to medium-pressure applications. At the low-pressure end, pumps do not continuously send water down the drain as do aspirators and there is no contaminated oil
Light microscopes, which view objects illuminated by visible light, have been around for centuries. Related are instruments that image nonvisible infrared or ultraviolet radiation, or ones that view fluorescence or Raman effects. All of these use opt
Total organic carbon (TOC) analyzers are a mainstay in industries that must detect and quantify carbon content from many samples and sources. Unlike spectroscopy, which measures specific carbon species from their unique interactions with light, TOC a
The prospect of gas cylinder accidents inspires awe and fear in lab workers. However, a safer alternative exists for some of the more common specialty gases: on-site or point-of-use generation that uses membranes, catalysts, or pressure swing absorpt
Lab refrigerators and freezers are similar in construction to household units, and come in a variety of temperature ranges, shapes and sizes. Freezer and refrigeration options fall into four general temperature categories: +4ºC refrigerators
Refractometers are instruments that quantify and identify chemicals and materials based on their refractive index (RI). A unique property related to the speed of light as it passes through a substance, RI is defined as the ratio of the speed of light
Best practices dictate that pipettes undergo preventive maintenance and calibration at least once per year. Calibration involves dispensing set volumes of a liquid, usually water, into the weighing pan of a calibrated balance.
Power supplies provide steady, precisely controlled electrical energy to electronic equipment. One type of supply, the uninterruptible power supply, powers electronics in the event of an emergency by keeping a battery constantly charged. When the
First introduced by Beckman in 1936, pH meters have become a mainstay of academic, industrial, and manufacturing laboratories. pH meters determine the acidity or alkalinity of a solution by measuring the concentration of hydrogen ions; H+; or, more a
Most laboratory workers view ovens almost as utilities, using them principally for drying glassware and heat-resistant equipment, regenerating desiccants and catalysts, gently heating samples, and curing or preparing materials and composites.
